“…This folding of optical pathways can be implemented by arranging flexible small diameter plastic optical fibers (POF) in a 2D-array configuration [9][10][11]. Also a flexible fiber-imaging guide (FIG) can provide a solution here [12][13][14]. Both guidedwave based OPBs have the advantage of being well suited to bridge interconnection distances from a couple of centimeters up to a few tens of centimeters, since the light does not suffer from beam diverging effects as it remains confined to the wave-guide.…”

In this paper we present different configurations for a compact free-space optical interconnection (FSOI) module by combining two radial gradient refractive index lenses (GRIN) and/or two arrays of refractive microlenses. Based on our findings with ray-tracing and radiometric analysis we discuss how we have selected the proper optical system configurations and how we have chosen the different design parameters to optimally accommodate different types of opto-electronic emitters such as LEDs, micro-cavity LEDs and VCSELs. We hereby focused on maximizing optical coupling efficiencies and misalignment tolerances while minimizing inter-channel cross-talk. Furthermore we discuss the experimental optical characteristics of two such prototype modules that we completed together with the first experimental results of their use in parallel data communication demonstrator systems.
